StalAge

StalAge is an R (R Core Team, 2016) code developed to construct age models for speleothems (Scholz and Hoffmann, 2011; Scholz et al., 2012). It was specifically designed to construct speleothem age-depth models based on 230Th/U-ages, but it can also be applied to other archives and age data.

StalAge was originally developed for R 2.10.1. In principle, StalAge also works with the most recent version of R, but a few problems/crashes have been reported. Thus, we recommend using version 2.10.1 of R to guarantee accurate application.
